HYDRAULIC PUNCHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 404,633, dated June 4, 1889. Application tiled November 7, 1887. Serial No. 254,729. (No model.) Patented in Germany February l2, 1887, No. 41,746l

.To all whom, if may concern:

Be it known that we, vCONSTANTIN C ARL KLINIK, FRIEDRICH PINKowsKI, and AU- GUsT GROSS, of Knigshiitte, in the Kingdom of Prussia and German Empire, have invented new and useful Improvements in Hydraulic Punching-Machines, of which the following is a specification, reference being had therein to the accompanying drawings, no

1o patents being obtained by us anywhere for this invention except in Germany, February l2, 1887, No. 41,746.

Our invention relates to hydraulic motors and the application of the same to mechanical I5- devices; and it consists in an improved construction of hydraulic motor and press applied to a punching-machine, as hereinafter described and claimed. Y

In the accompanying drawings, Figure-l 2o represents a vertical section of our device,

showing the operating mechanism. Fig. 2 is an elevation, certain parts of the device being shown in section. Fig. 3 is a horizontal section taken on line a h of Fig. l. Fig. 4 is a like section on line c d of Fig` 1. Fig. 5 is a detached view of a plate which forms a housy ing for connecting gear-wheels. Fig, 6 is a section taken on line e f of Fig. l.

In the drawings, A designates the liquid- 3o reservoir, the base C of which is screwed on the cylinder B, Within which is placed a pressing-piston K. The reservoir and cylinder are further secured by bolts a and securing-nuts, as shown. The threaded surface of the cylinder B is formed on a ring, which is driven in place on the cylinder in a heated condition, and thus firmly secured. The base C is provided with threaded holes F for the attachment of handles to be used in attaching it to or removing it from the cylinder B.

lVithin the reservoir A are placed two pumps P P2, the lower extremities of the pump-cylinders being screwed into perforations through the base of the reservoir, as shown. The pump-cylinders are provided with lateral valves P, through which liquid is drawn into the cylinders during operation.

The rods d of the pump-pistons are connected, as shown, with a crank-shaft XV, having bearings in the upper part at the joint .and a gear-wheel 7L' is placed on the shaft,

said wheel engaging with a smaller gearwheel r. made solid therewith, and has bearings in the casing of A and in a removable plate E, which forms a housing for the wheels h and 7^. A crank F may be applied to either of the shafts WV m, according to the speed of rotation of the crank-shaft required. The piston K, being provided with packing, iits in thecylinder B and forms a pressure-head for the stock n of the cutting-tool o, extending downward, as shown. A small passage s forms communication between the reservoir and the cylinder B, said passage being opened or closed by means of a screw-valve o, which is provided with a handle q. The passage s is kept closed during operation, and is opened to remove the pressure of liquid from the head K in the cylinder.

A spiral spring S is placed under the head K in the cylinder for the purpose of raising the head when it is released from the pressure of the liquid.

The pumps being operated by the rotation of the crank-shaft, liquid in the reservoir is drawn through valves P into thc pump-cylinders and is pressed down into cylinder B against the head K, which is forced downward, thus actuating the cutting-tool. W'hen 'the work is completed, the valve o is opened, allowing the passage of liquid from cylinder B to the reservoir, and the head K, being released, is immediately raised by the spring S.

We claim- The combination of the reservoir A, the cylinder secured to the base thereof and having the pressure-piston, the pumps arranged withroo The wheel r is on a shaft m, being 65 i in the reservoir and having their lower ends screwed to the base thereof, the cap D, secured to the uppeil end of the reservoir, said cap and reservoir having the bearings formed in their meeting ends, the plate t, secured to the cap and reservoir, the housing E, bolted to the cap and reservoir, the crank-shaft journaIed in the bearings in the reservoir and cap and in Openings in the plate t and housing E, the cranks of the said shaft being connected to the pump-p1ungers, the Wheel 71J on the said shaft, the shaft m, journaled in bearings in the housing,` and in the reservoir, and having the pinion 1, meshing with Wheel h, and the crank F', adapted to fit on the outer ends of 15 either the crank-shaft or shaft m, substantially as described.

In witness whereof we have hereunto Set our hands in presence of two Witnesses.
